FiDECIFICATION forming part of Letters Patent No. 325,274, dated September 1, 1885.

Application filed October 13, 1884 (No model.)

To ctZZ whom it may concern:

Be it known that I, STILLMAN W. ROBIN- soN, of Columbus, county of Franklin, State of Ohio, have invented an Improvement in Machines for Uniting Soles and Uppers of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to and is an'improvement upon the machine described in United States Letters Patent No. 297,718, granted to me April 29, 188i, and to which reference may be had, the object of my invention being to simplify the construction and operation of the said parts, whereby the wire may be more accurately driven and partially turned and cut off, and whereby the horn may be raised and lowered automatically and the shoe or boot be more accurately fed over the horn.

The novel features of my invention will be fully described in the following specification, and will be thereafter specifically set forth in the claims at the end of the specification.

Figure 1 is a front elevation of a machine embodying my improvements. Fig. 2 is a left-hand side elevation of Fig. 1; Figs. 3 and 4., details of the feed and devices to keep it in proper position with relation to the edge of the sole. Fig. 5 is a longitudinal sectional detail of the working-head. presser-plate-carrying sleeve, spindle, and cutting mechanism; Fig. 6, a partial section of Fig. 5 in the dotted line a"; Fig. 7, a section in the line 00 50*. Fig. 8 is an under side view of the tappetring, to be described, which actuates the camring; Fig. 9, a side elevation, partially broken out of the said ring in Fig. 8; Figs. 10 and 11, a top and side elevation of the camring; Figs. 12 and 13, respectively, under and inner side views of the grippencarriers; Fig. 14, a side elevation'of one of the grippers; Figs. 15 and 16, an inner side View and section of one of the wire'detainingjaws. Fig. 17 is a detail in side elevation of the spindlehead; Fig. 18, an enlarged view, chiefly to show the cutters and the devices for operating them; Fig. 19, a section of Fig. 10 in the dotted line 3 y,- Figs. 20 to 22, details of the cutting mechanism; Fig. 23, a top view of the presscrlate. Fig. 24 is an under side view of the collar fast upon the lower end of the spindle; Fig. 25, a detail to illustrate the devices for rotating the spindle; Fig. 26, a detail of the shoe-feeding device; Fig. 27, a rear side elevation of the rod-controller, and Fig. 28 a detail to be referred to.

The frame-work A of the machine, of proper shape to support the various parts, is pro vided with suitable bearings for the main shaft A, having fast upon it two pulleys, A A which receive a driving-belt, the difference in the diameter of the said pulleys enabling the machine to be run at a faster or slower speed. The shaft A has at its inner end an offset, A", provided with a crank-pin, A that enters a hole in the end of the knuckle piece A, the said crank piu also passing through a hole made in the pitnian B, which at a point below the crank-pin A is pivoted or jointed by apin, 2, directly to a collar or head, 4, which is attached to or forms part of the upper end of the working head D, so that the pitman imparts a uniform reciprocating movement to the working-head whatever may be the thickness of the stock, as in my patent referred to. Theknuckle-joint piece has abackwardextension, (see Fig. 25,)which, byavertical pin, a, is connected with one end of ayoke, a,haviug its fulcrum upon a vertical rod, a held rigidly by the frame-work A. The free end of the yoke a, bent around to the front of the machine, has pivoted to it a link, a, bored at its end farthest from its yoke to embrace loosely and slide on a pin, a held in cars of a collar, C, fixed by screws 1) and spline 1) upon the hollow oscillating spindle B, made in parts, as will be described, through which and the parts B 13 within it is passed the wire or fastening material to, which is to be inserted into the sole and upper and then partially turned therein, as described in the patent referred to. The rotation of the shaft A through the end of the knuckle-joint piece A causes the yoke a to slide up and down upon the fulcrum-pin a and the link a" to slide on the pin a, and at the same time the said crank-pin and knuekle joint piece cause the yoke a to be vibrated about the fulcrum-pin a as a center, thus rotating the spindle, when desired, for about a quarterturn in either direction,as will be described. The pressor-plate carrying sleeve'e, interposed between the spindle B and the working-head D, hasacollar,6,screwed upon its upper end, (see Fig. 5,) which is jointed to a lever, d, having its fulcrum upon a link, If, in turn pivoted at 1) upon an ar1n,b", of the frame-work. The lever d is normally held down by a spring, I), attached to an ear, I), and the spring is joined by a link, 5, with the said lever, the collar 6 of the sleeve 0 being thus normally kept pressed against the top of the working-head D, so thatthe sleeve 6 rises with the working-head; but the descent of the sleeve, aswill be described, will be arrested sooner orlater during the descent of the working-head, according to the thickness of the stock on the horn. presser-plate-earrying sleeve 0 has attached to or forming an integral part ofit a bearingplate, 0, provided with pins or studs 0 6 which serve as fulera for the working levers or arms E E, with which are adj ustably connected the blades or cutters 7 8, (see Figs. 5 and 18,) which act to sever the fastening material after the end thereof has been inserted into the stock resting on thehorn. Thelower arms or ends of the rocking levers E E are forked or provided with ears for the reception of the cutter-holding clamping-blocks E E each being bored for the reception, and split and provided with a clamping-screw, 10, for the retention of one of the cutters.

To adjust the cutters longitudinally, each block is provided with a hole in which is placed the transverselyslotted plug a, which is acted upon by the adjusting-screw 12, the inner end of the plug bearing against the rear end of the shank of the cutters 7 or 8, the slot in the plug affording a passage for the pin 17, which supports the said block in its lever E or E. Portions of the rocking arms E E are provided with teeth, (see Fig. 18,) so that they are compelled to move together, the arm E deriving its movement from the arm E, the latter having teeth 13, which, at the termination of each partial rotation of the spindle B, are acted upon by the teeth of the rackbar E fitted to slide in guides in the bearingplate 6, a screw, 14, inserted through the said bar and extended into a slot, 15, in the plate 6, guiding the said rack-bar during its reciprocation in opposite directions by the projection 16, formed by cutting away a part of the collar B forming part of the lower end of the spindle B, the said pin 14 being notched or cut away to serve as one of the corners against which the projection 16 strikes when the levers E E are turned to separate the cutters. The presser-plate e is countersunk at its upper side, as at 6 to receive the conical lower end, 18, of the spindle-head B and below the surface against which the conical end of the spindle-head rests the said presser is provided with two holes (see Figs. 5 and 23) which receive and guide the cutters or blades 7 8, the

presser-plate, when the cutters are opera ed to sever the fastening material close to the stock, being held stationary. The collar B,

The lower end of the at the lower end of the spindle B, serves as a shoulder against which the lower end of the presser-plate-carrying sleeve 6 bears, the latter, when permitted to descend under the action of the spring I) and lever d, as is the case while the working-head D is being depressed, descending with the said sleeve until the presser-plate meets the stock on the horn H, further downward movement of the working head causing the grippers then grasping the wire to drive the same into the stock. The spindle B, made as a sleeve, is provided with a removable hollow center piece, 13, having a passage, B for the wire'w. The spindle near its upper end has a shoulder which receives against it the collar 19 of and supports the center piece, E the latter being prevented from rising therein by the hollow nut 20. The center piece is screw-threaded at its lower end for the reception of the head B of the spindle B, containing the wire-grippers d their actuating devices, and the wire-detainers, as will be described. The upper end of the spindle-head is inserted into the open lower end of the spindle B until a projection, 70, thereon enters one of the notches 71 (see Fig. 24) in the collar B, the said projection and collar preventing rotation of the spindle-head in the spindle, and thereafter the center piece thrust down through the spindle is screwed into the spindle-head; but before the spindle-head is so applied to the spindle, the head is provided with all the devices to be carried by it. The spindle-head B for part of its length (see Fig. 5) to form spaces for the reception of the toothed wire-grippers d which grasp the Hat sides of the wire 10, the said grippers, one of which is shown in Fig. 14, having at their upper ends hooks 22, and at their lower ends projections 23, the grip pers being fitted to slide freely in the slots of the said spindle-head in which they are placed. The spindle -head B at a point above the slots referred to, is slotted or cut through at right angles thereto, as at 7 2, (see Fig. 17,) to

is slotted near its lower end from side to side 4 form openings for the reception of the two serrated or toothed detaining jaws or blocks d, one of which is shown in Figs. 15 and 16, said jaws placed in the said opening, as in Fig. 5, being acted upon at their rear sides by fiat springs d", (see Fig. 6,) interposed between them and the spindle-head B, the said springs causing the said jaws, which, preferably, are serrated, to act against the flat sides of the fastening material or wire, or to prevent the same from being lifted. while the grippers d relaxed from the fastening material, are being raised in unison wit-h the w orking-head D to obtain a new hold on the wire and thrust or force the end thereof into the stock on the horn H. The detaining-jaws d, at their rear sides, are provided wit-h projections 65, (see Fig. 16,) which come to a bearing against the sides of the slot 72 whenever any severe twisting-strain in the wire tends to reverse it between the said jaws; and to preventthe jaws from coming togetherwhen the wire is absent one of the said jaws is provided with pins 66, which at such time abut against the opposite jaw. The working-head D is slotted near its lower end, as at 42, (see Fig. 6,) to receive the screw 43, which is first extended through a washer, 44, the end of the said screw entering the tappets-ring G, and confining the same in fixed position with relation to the said head, the adjustment of the screw 43 in the slot 42 altering the position of the said tappet-ring G with relation to the working-head and the oscillating stroke of the spindle and spindle'head, so as to cause the wire-grippers to be thrown into engagement with the wire with more or less force. The farther the screw from the right-hand end of the said slot, viewing Fig. 3, the more severe will be the grip of the grippers upon the wire. Thelower end of the tappet-ring G has two tappets, 4.3,(see underside view and elevation, Figs. 8 and 9,) and at its upper end the said ring has an inwardly-extended shoulder or flange, 47, which is grooved at opposite points for the passage of the hooked upper ends, 48, of the g1 ipper-carriers G. (Shown separately in Figs. 12 and 13.) The gaps or grooves in fiange 47 are filled in with flushblocks 46, which are attached to the tappetring by screws 52 after the hooks 48 ot' the gripper-carriers have been passed above the flange 47, the fiushblocks enabling the formation of a smooth race on which the hooks 48 slide as they are moved in the arc of a circle by the spindle and spindle-head in their oscillation. The lower ends of the gripper-earriers G are made segmental in shape to take an extended bearing in the tappet-ring, and are provided at their concaved sides with hooks or projections 49, that enter the longitudinal grooves of the spindlehead salso do the portions 53 of the said carriers, the portions 53 and the projection49 both sliding up and down in the said grooves in unison with the tappet-ring G and working-head D.

The wire-grippers (1 provided at their up per ends with the hooks and at theirlower ends with shoulders 23, are extended up through a cam-ring, 55, provided externally with two projections, 56, and internally with two eam-surfaces, 57.

To assemble the parts the wire gippers d are placed in the cam-ring 55, and the latter on the spindle with the wire-grippers in the longitudinal slots of the spindle-head, and the hooks 22 of the grippers, extended above the said cam-ring 55, are made to engage the projections 49 of the gripper-carriers supported by the tappet-ring, the cam-ring thus resting loosely upon the shoulders 23 of the grippers, andjust below but free from contact with the lower end of the tappet-ring G. The canrring acts to keep the wire-grippers in the longitudinal slots of the spindle-head, and as the cam-ring is rotated on the spindle,the cam-surfaces 47,acting on the grippers, force them against the wire. The tappets 45 of the tappctring G enter the wider spaces 58 between the projections 56 of the cam-ring 55, and as the cam-ring is partially rotated with the spindle-head its corners 59 or 60, according to the direction of rotation of the spindle and collar, strike the tappets 45, and the camring is stopped thereby while the spindle continues to turn, which results in moving the cam-ring on the spindle, the grippers being forced toward each other or being permitted to loosen their grip on the wire, according to the direction of rotation of the spindle when the cam-ring is arrested by the tappets 45. From a little before the end of the downstroke of the spindle to the time that the wire is cut off the shoulders 59 of the cam-ring rest against the tappets 45, and immediately after the wire is severed the rising spindle commences to turn in the direction of the arrow next to it, (see Fig. 25,) carrying the cam-ring 55 with it, and just before the spindle approaches its highest point the corners 60 of the said cam-ring are brought against the tappets 45, and by the time that the spindle reaches its highest position its continued further rotation causes the cam-ring resting against the said tappets to be turned on or with relation to the spindle in the direction to compel the cams 57 of the cam-ring to force the grippers d inward upon and so as to grip the wire, the cam-ring and tappet-ring occupying substantially the same position until the spindle reaches nearly its downstroke, and during the lower stroke the spindle is rotated in the direction opposite the arrow, Fig. 25, causing the movement of the cam-ring in the proper direction to bring its projections 59 against the tappets 45, when, during a slight further movement at the extreme lower part 01' the stroke, the grippers are released. The upper end of the spindle B is provided with a projection, f, with which a spindle-arresting device, shown as a pivoted latch, f, may be engaged when it is desired to arrest the descent of the spindle,as is frequently the case as when, for instance, thehorn is not provided with a boot or shoe, or when the wire is to be projected down into the nose and through the same preparatory to starting the machine. The pitman B, at or near its lower end, has a hook (see Fig. 2) which, during its ascent, is adapted to catch upon the upper hooked end of either the trip-rodf or the horn-lifting rod f, to thus effect the lowering and raising, respectively, of the horn H through the hornlifting mechanis1n,t0 be described. \Vhen the trip-rodf is lifted to lower the horn H, the threearmed lever f (see Fig. 2,) to which the said rod is connected, is turned upon its fulcrum, so that its arm 30 in engagement with the wedge f is withdrawn from below the lower end of the horn-spindle f The upper end of the horn-spindle is provided with an annular groove, (see Fig. 1,) which is entered by the forked end of the lever 31, with which the lifting-rod f is connect-ed. The rodsf andf are moved into position to be engaged too the one or the other by the hook of the pitman B, according as it is desired to lower or raise the horn by means of a rod-controller,g, pivoted at 32, the said controller being connected atits rear end to a spring, 51, which acts normally to cause the rod-controllerprovided at its rear side (see Fig. 27) with. two sets of pins, 83 84., between which are placed, respectively, the rods f and f -to keep the trip-rod f in the range of the hook of the pitman B, to depress the horn as the working-head reaches its most elevated position. The rod-controller g is joined by a wire, 9, or other suitable connection, with a treadle or lever, 9 pivoted at 9, so that the operator, by depressing the said treadle and operating the rod-controller, is enabled to engage the lifting-rodf with the hook of the pitman B, to lift the horn H into position after the boot or shoe has been placed upon it. The first part of the upward movement of the rodf and the lever 31 lifts the horn to its proper level, and as the lever 31 completes its movement, the link 9 connected therewith and with the three-armed lever f, turns the latter in the direction to cause the arm 300i the said lever to force the wedge f under the lower end of the horn-spindle, thus locking the same in position positively before the presser plate comes down upon the work.

Referring to the feeding mechanism, the frame work (see Fig. 26) has attached to it at its rear side a sleeve like hearing, it, which receives a shaft, h, provided with a handle, h", by which to turn it, the other end of this shaft having an eccentric pin or projection, h which, by the partial rotation of the said shaft, serves as a back stop or rest, against which may act the lower end of a cam rod, h, pivoted at h on a lever, 33, the inner end of which (see Figs. 2, 25, and 28) is pivoted to the pitman B, the descentof the said canrrod in contact with the feeding-dog in, normally held back by a spring, m causing the said dog to be moved forward toward and against the edge of the shoe or boot on the horn H. The position of the eccentric pin h determines, it will be understood, the position of the front end of the feeding device with relation to the nose and tip of the horn, thus enabling the operator to control the insertion of the fastenings at a greater or less distance from the edge of the sole. The rear end of the feeding-dog m is placed in a guide-block, or", having a pivotpin, m, which is inserted in the bearing h, the said pivotpin being parallel with the shaft h.

In the slot in the frame-work in which the feed-dog is made to vibrate horizontally I have placed an L-shaped dog, m pivoted at 35, the rear beveled side of which is operated upon by the lower wedge-shaped end ofalever, 36, (see Figs. 25 to 28,) pivoted at 38 (see Figs. 2 and 28) upon the frame -work, the upper end of the said lever being connected by a pin, 37, with the lever 33, before described, which has its front end pinned to the pitman B, that operates the workinghead l), the said lever 33 carrying, it will be remembered, the camrod 71 A piece, 67, attached to an arm of the frame-work and provided with two stops,limits the movement of the rod-controller 9. At the outer side of the framework, near the handle h (see Fig. 1.) are two suitable stops, 68 and 69, to limit the movement of the said handle.

To vary the feeding movement of the feed dog m,l have pivoted upon the front of the machine a hand-lever, n. The lower end, acting against the dog mireferred to, may be made to arrest its backward movement, and consequently of the feed-dog m sooner or later, to thus correspondingly lessen or increase the effective stroke of the lever 36 upon. the inclinedback of .thedog m in its next movement. The lever it, placed between the stops 75 and 76,may be moved by hand while the machine is in motion, to thereby vary the spacing between the fastenings, as may be desired. The stops 75 and 76, cooperating with this lever a are made adjustable,(see Fig. 1,) so that the operator may have one stop for spacing about the fore part and another for spacing in the shank, moving the lever 12 in contact with first one and then the other of the said stops. The spool o,upon which the threaded fastening material to is wound, is composed of two side plates held together by suitable bolts, the flanges of the heads being preferably slotted or provided with holes to enable the operator to observe the quantity of .wire thereon. The spool-holder o is a concaved bracket having suitable flanges to receive the spool, the bracket being open in suitable manner at its under side for the passage of the wire 10 from the spool down through the spindle.

To produce the proper amount of friction upon the wire,I have provided the spool-holder with a friction-pad, 0 operated upon by a spring, 0 the pad resting on the wire.

The stop p on the rod f enables the forward end of the feed dog on to be held down next to the tip of the horn H when the same is in its lowest position, so that the edge of a shoe when applied to the horn comes directly against the end of the feed-dog, and as the horn is raised the rod f and stop 1) also rise, permitting the feed-dog m, the front edge of which is in contact with the edge of the sole, to rise with the shoe and horn without obstruct-ion until the dog arrives in substantially horizontal posi tion, after which the feed-dog is moved to feed the shoe on the horn.

The particular stop 1), herein shown as made adjustable on the rod f, is not herein claimed by me either singly orin combination with the rodf nor do I herein claim the mechanism shown for raising and lowering the horn or keeping it raised, as such mechanism, together with means for controlling the vertical position of the outer end of the feed-dog with relation to the tip of the horn, is made the subject-matter of another application, Serial No. 152,570, filed by me January 12, 1885.

The working-head 1) in this my present invention receives within it the nose or pressercarrying sleeve,and the spindle is placed centrally with relation to and has its bearings in the said sleeve, which results in a very compact arrangement of parts.

The cutters are operated positively in both directions, and thehorn is raised and lowered at the proper times mechanically.

I do not herein broadly claim a cam-ring by which to operate the grippers, as such camring, combined with the grippers, slotted spindle-head, and working-head D, is made the subject-matter of broad claim in my application Serial No. 152,571, filed January 12, 1885.
